Description

Grade 4234 is sioplas (two steps) silane XLPE compound and suitable for 1kv and below low voltage cable, it is composed by 95% silane crosslinkable low density polyethylene (compound A) and 5% catalyst (compound B). The product has outstanding performance in high speed extrusion, smooth cable surface, wild processing temperature, easy processing and convenient to use.

Standard

After crosslinked in the tepid water, the cable made from our product grade 4234 can comply with the standard of IEC60502-2004, GB/T12706-2002.

Typical values were tested on the 1mm sample strip by squeezing film extrusion after mixing compound of A& B (at percentage of 95:5) and be boiled in hot water at 90℃for four hours.

*Especially, these typical values were tested by press moulding sample under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃water for four hours.

Recommended Processing Technique

1. Extrusion Equipment

Most extruders for PVC and PE suit for 4234.

The recommended equipment and processing technique isas following.

Ratio of length and diameter 18—25:1

Diameter 45—120mm

Ratio of compressing 1.5—3.5

Ratio of elongation 1:1.0—1:1.5

Filtering mesh 40/60/40

2. Extruder processing temperature and other related settings

Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are asfollowing:

Feeding Section（℃）

Compression Section（℃）

Measurement Section

（℃）

Die head and Mould

（℃）

130~155

155~170

170~180

180~200

Die head setting: Squeezing extrusion style is recommended

Cooling water temperature: Should not beless than 25℃,gradual cooling water tank is recommended.

3. Crosslink

After extrusion and cooling, the cable can be crosslinked by immersed in hot water (90℃) or exposed in low pressure vapour. The time required for crosslink is based on the thickness of the insulation and the coil size, the thicker the insulation and the greater the coil size, the longer the crosslink time required. The crosslink time can be calculated according to the equation of 4hr/mm for 90℃.

Q: Apple 6splus charge may not support this accessories how to do more: Sometimes no way, the problem to the owners to solve the common, must wear, the owners agreed

Q: Ipad not charge how the matter. Said the cable or accessories have not been certified, and may not be able to cooperate with this ipad reliable work....: Several sets of cables in the same height of the laying, the adjacent cable between the bridge should be considered maintenance, maintenance needs, generally not less than 0.6m. This is just a matter of theory, it does not matter. Anyway, the actual construction is to do so,

Q: What is the difference between wires and cables?: The introduction of the device in the form of: sealing ring (sealing ring is to achieve the required protection level of the shell and the use of cash-saving brush to help find the silent material or elastic material parts) type of introduction device; casting solidified packing seal Type introduction device; metal seal ring introduction device

Q: How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more: Can not be removed, and so on after the first line of fluoride, and then demolition of air conditioning.

Q: Wire and cable CCC product consistency is what: PVC line, the market is better with plastic, plastic, . Wantong, etc., if only home improvement, then the brand requirements do not need so high. Small brands are the same, we see the quality. Network cable, then preferred Ann or TCL.

Q: Apple 6 Charging Why always show this cable has not yet been certified: And I answered the other person's question is very similar: . the line of the banding distance of not more than 1.2 meters, the two ends of the wire box outlet tube 15CM should be ligation; . casing embedded, then through the basement wall, the surface must be installed rigid Waterproof casing, that is, steel pipe + water ring; through the fire pool, living pool: flexible waterproof casing; (wing ring specific practices can be collected online related Atlas); through the floor, according to whether the design requirements , Under normal circumstances PVC casing on it. Note: . rigid waterproof casing, flexible waterproof casing is a one-time reserved in place, through the floor of the casing of the flower lamb to suppress the barge of Xi Jie Xi Xi shou, is the first stay hole, when the installation of riser Casing, because the floor casing has every layer, the location of the reservation will always be biased, in order to ensure vertical vertical pipe, and finally unified hanging line repair hole and then install the riser and casing. . now most of the bathroom are dirty, waste and diversion, and more of the riser, and so on, the air conditioning casing of all the shear wall should be embedded, to avoid the subsequent damage to the structure of drilling (no stay can only drill) Note that the location of the hole and the installation of the riser will affect the opening of the toilet window. . the casing is the casing, riser is the riser, casing than the riser model 1 to 2 level. . plate at the end of flat, board 2 to 5CM higher to see if you need to do leveling layer.

Q: Why this cable has not yet been certified: Electromechanical products are usually used to be assembled into parts, multiple parts and then assembled into a single product, the number of products or the number of pieces measured

Q: This cable or accessory has not been certified and may not be able to work with this iphone reliably: The operation of the hydraulic pipe is very simple to see it will engage in their own, embedded more simple, and then get the construction site in accordance with the requirements of the drawings put away, tied with tie wire on the OK Mouth up the pipe to use cement bag to prevent good, to prevent the infusion of concrete, so buried even if the end

Q: If you want to sell wire and cable, then what to do in advance to detect? The The The The The: Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.

Q: What are the T and T, s of the wire and cable test type?: The expression is not very clear, it should be said to wear a tube, if a single wear on the line 100. Outside diameter 60mm.
